ISO ASTM DIN shore D Durometer Hardness Tester For Measuring
Plastics / Silicone Rubber
Introduction
A reliable instrument for measuring the impression hardness of soft
materials such as coatings, plastics and rubber. Equipped with a
drag indicator, which holds the highest measured result. Delivery
includes metal test block.
Analog durometer is the ideal choice for a wide range of Shore
hardness measuring applications. Durometer displays hardness
readings on an easy-to-read analog scale calibrated in 0 to 100
Shore units. Other scales
are available: A, C, D, DO, O, OO.
Analog durometer conforms to:
ASTM D-2240, DIN 53505, ISO 868, ISO 7619,
Optional accessoires:
- standard rubber test blocks
- Operation test stand
Durometer type D for materials such as polyester, ABS, nylon, polyurethane, kevlar,
acryl, wood, polystyrene etc..
Range: 0 -100 points
Accuracy: 1 point
Dimensions: 102 x 57 x 44 mm
Testing Procedure
1. Place the instrument on the material to be tested. The durometer
must be level and perpendicular to the specimen. Any angle other
than perpendicular (90°) may cause errors. The gauge is equipped
with the Memory Pointer make sure the pointer is returned to zero
before starting.
2. Press the foot of the gauge firmly against the specimen, but not
so firmly as to imbed the foot into the surface of the material.
3. Maintain pressure for 2 to 3 seconds. The dial hand gives the
reading in durometer points.
IMPORTANT: After the initial reading has been noted, continue maintaining
pressure for several more seconds. Creep or cold-flow of the
specimen, if present, will be evident by receding action of the
dial hand.
4. Repeat above steps for each use. An example of a properly noted
durometer reading: “Durometer A 61, Creep 7 at 15 seconds, 73°F.”
Memory Pointer
The Memory Pointer moves with the measurement pointer when a
measurement is taken.However, when pressure on the specimen is
released, and the measurement pointer returns to zero, the Memory
Pointer
remains in position, marking the last measurement.
To return the Memory Pointer to the zero position prior to taking
another measurement, rotate the knurled knob on the face of the
instrument counter- clockwise until the pointer has been reset.
